Today's social multimedia technology is quite developed, and most of them benefit from the advancement of semiconductor components or display devices. In terms of display devices, liquid crystal display benefits with superior properties such as high quality, good space efficiency, low power consumption, and independence have gradually become the mainstream of the market. Generally, liquid crystal displays can be classified into three types: transmissive, reflective, and transflective. The semi-transparent semi-reflective liquid crystal display can be used in both light and light conditions, so it can be applied in a wide range. In the case of a transflective liquid crystal display, it can simultaneously display using a backlight and an external light source. In general, the transflective liquid crystal display i includes a halogen (tetra) substrate, a counter substrate, and a liquid crystal layer interposed between the two substrates. The halogen structure on the halogen array substrate has a transmissive disk reflection region 'and a transflective electrode is disposed in the transmissive region, and a reflective halogen electrode is disposed in the reflective region. The all-transparent semi-reflective liquid crystal display is in the form of a full-color through-screen and a black-and-white reflection. By using f, a reflective layer having a convex structure is used in the reflective area so that ambient light can be uniformly dispersed, so that various viewing angles of the reflective area can be normally displayed. However, such a semi-transparent half 201133043 AUUyiU〇88 33467twf.doc/n reflective liquid crystal display has a disadvantage that its black and white reflection picture tends to be yellowish.

The second substrate position is the opposite of the first substrate. The color filter patterns are respectively disposed in the sub-tenox regions of the penetration regions of the first substrate or the second substrate. The single complementary color filter pattern is disposed in the sub-pixel region of the reflective region of the first substrate or the second substrate, wherein the secondary halogen region of the reflective region is completely covered by the complementary color filter pattern. The display medium is located between the first substrate and the second substrate. The present invention provides a color filter substrate comprising a substrate, a plurality of color filter patterns, and a single complementary color filter pattern. The substrate has a reflective region and a transmissive region, and each of the reflective region and the transmissive region has a plurality of secondary halogen regions.
